People crazy enough to be drag racing have been injecting nitrous oxide into their engines for decades.
Today’s invention offers a new way to gain extra speed off the line whilst not decreasing the danger.
A two-cylinder version of the engine envisaged is shown. Each cylinder has a tank of nitrous oxide with an electronically controlled outlet valve.
When one of these is opened, a stream of oxide passes into a hybrid rocket motor (orange) where it is ignited. This combustion process drives the conventional engine’s piston.
The gas valve then closes, ignition ceases and the exhaust stroke is shown in the bottom picture.
Safe? No. Fast?…potentially, albeit with an engine change every 200m.
